PETER BERTGES, OF ALLEGHENY, PENNSYLVANIA.

WINDOW.

SPECIFICATION forming part of Letters Patent N 0. 718,596, dated January 20, 1903.

Application filed July 1'7 1902. Serial No. 115,906. (No model.)

To all whom it may concern:

Be it known that 1, PETER BERTGES, a citizen of the United States, residing at Alle gheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Windows, of which improvement the following is a specification.

This invention relates to certain new and useful improvements in windows, and relates more particularly to the window-sash.

The object of the present invention is to provide a window frame and sash in a manner that will permit the window-frame to be extended in a horizontal position in order that it may be easily cleaned without the necessity of cleaning the window from the outer face, as is usually the case.

The present invention further aims to provide a device of the above-described character that will be extremely simple in construction, strong, durable, comparatively inexpensive to manufacture, and highly efficient in its use.

In describing the invention in detail reference is had to the accompanying drawings, forminga part of this specification,and wherein like numerals of reference indicate like parts throughout the several views,in which-- Figure 1 is a perspective view of my improved window, showing the sash in a horizontal position as it appears when the same is to be cleaned or when it is desired to obtain a greater amount of ventilation than is possible by the raising or the lowering of one of the window-sash. Fig. 2 is a front elevation of the same, partly broken away, showing more clearly the pivotal connection of the window-sash and the guides and the means for locking same. Fig. 3 is a vertical sectional view taken on the line 3 3 of Fig. 1, looking in direction of the arrow. Fig. 4 is a perspective view of the weight. Fig. 5 is a detail vertical sectional view of the look.

In the drawings the reference-numeral 1 represents the window frame, having the usual guideways 2 2 formed therein. In said guideways are slidingly arranged guides 3. These guides 3 are pivotally secured on each side, as shown at 4, to the window-sash 5 and are secured on each side at their upper extremity by means of the spring-lock 6, which is secured and arranged in the top rail of the window-sash.

The reference-numeral 7 represents the weights, and 8 the sash-cord,which is attached to the guides in the ordinary manner.

The spring -lock 6 consists of a spring pressed locking-pin 9, the spring being indicated by reference-numeral 10, and is secured in the upper side rails of the window-sash. Said springpressed pin extends through plates 11 and 12, the former being carried by the window-sash 7 and the latterby the slide 3. Upon this locking-pin 9 is also secured the head 14, carrying the knob 15, said knob 15 extending through the slot 16, formed in the plate 17, carried by the upper rail of the window-sash.

The operation of my improved deviceis as follows: When itis desired to'place the window in the position as indicated in'Fig. 1 of the drawings or in dotted lines of Fig. 3 of the drawings, the knobs 15 are operated inwardly, thereby releasing the window-sash from the guides, which form the locking engagement therewith when in their normal position. When the sash has been released, the same will then be easily swung downwardly, as shown in Figs. 1 and 3 01": the drawings, by reason of the pivotal connection 4. Both sides of the window may be easily cleaned and the window again placed in proper position.

The many advantages obtained by the use of my improved device will be readily apparent from the foregoing description, taken in connection with the accompanying drawings.

It 'will be noted thatvarious changes may be made in the details of construction without departing from the general spirit of my and guided by the wall of an elongated recess signed my name in the presence of two subin the sash, a knob having its shank portion scribing Witnesses. fastened to said collar, a slotted plate fastened to the face of the sash and through PETER BERTGES' 5 which the shank portion of said knob is In presenoe ofguided, as set forth.

In testimony whereof I have hereunto M. HUNTER.
